Which firmware?

I’ve got a MK2s that I upgrade to a 2.5s via the official kit. It has what I believe are the latest model extruder files and optical sensor.

What firmware should I be running?  I’ve got MK2 on there now, and I can flash 2.5s on it, but then it shows the dreaded 2 rows of boxes on screen and is unresponsive.  Prusa slicer says ‘firmware flashed success’ (as do the detailed logs)

If I flash MK2 back on it, that works and the LCD comes back to life.  I had always thought (and read) that the two rows of boxes meant you put the wrong firmware on.... but is there a trick to making what used to be a mk2s now think it’s a mk2.5s so it’ll run this firmware?

GitHub isn't exactly intuitive sometimes. At least nothing was bricked. Glad you got it going.
